The short version: On the free analyzer, your free score is generated on our servers from the code or files you submit; we do not store that input after scoring unless you upgrade to Interactive Code Review. Our Chrome extension journals invention sessions locally in your browser; see the extension section below.
For the free Patent PreCheck Score on the website, your pasted text, uploaded file, or GitHub import selection — whether code, a document, notes, or a conversation export — is sent to our servers for analysis (including our AI scoring provider) and is not stored in our database after your score is generated. We do not retain the full text of your submission in our systems. Your full GitHub selection may remain in your browser tab until you close it or upgrade; we do not copy it server-side for the free check.
If you choose Import from GitHub on the free analyzer or re-import during Interactive Code Review signup, you authorize our GitHub App to read only the repository paths you select via GitHub’s Contents API. We receive file contents for scoring and coaching — not your entire repository, commit history, or issues. For the free score we also store non-content metadata tied to your report (repository owner and name, branch or ref, and selected file paths) so you can re-import the same selection at signup; we do not store file contents from the free check. If you upgrade to Interactive Code Review, we store the imported code text you submit (paste_input) for up to 30 days as described below.
We do not keep the text you submitted for a free score. We do keep structured metadata, and that metadata is not anonymous once you give us an email.
Every successful free analysis writes a metadata row that includes a SHA-256 hash of the input, the numeric score, whether it passed the analysis gate, a technology-domain hint, the request source (for example web, GitHub, or the Chrome extension), and the time. That row does not include your email, IP address, or the submitted text. These rows are retained indefinitely; there is no automated 48-hour deletion job.
If you ask us to email the score, we also store a report and a lead record. The report holds the score metadata the engine produced (numeric scores, score band, USPTO pillar scores, narrative summary, recommendations, technology-domain hint, AI-contribution level, human-conception fields, and prior-art summary fields). The lead record holds your email address, the IP address we saw when you requested the email, campaign attribution when present (UTM parameters, click IDs such as gclid / fbclid / msclkid, landing path, and referring URL), opt-in flags, an unsubscribe timestamp if you opt out, and a link to that report. A SHA-256 of your address may appear in server logs for debugging. If you delete your data, we keep a one-way hash of the address so we can honour a do-not-contact request without holding the address itself. That hash does not block you from submitting the same address again later.
If you later purchase Interactive Code Review or Portfolio, we may also store an optional project label you provide, tied to your email and report ID.
If you opt in when you email your score, we may send legal-change notes to that address using the email and score metadata we stored for the report. Paid Interactive Code Review also includes a separate monitoring product. We do not reconstruct your original submission from stored metadata. Unsubscribe stops further email; it does not delete the stored records (see Data deletion below).
If you purchase Interactive Code Review or Portfolio, we store your name, email, report IDs, optional project labels, and entitlements (e.g. which codebases you have paid to review) so we can restore your sessions and billing. You can delete those records yourself from your account area, or email info@patentprecheck.com.
If you use the free score without entering an email, we have no way to contact you and we do not send legal-change alerts. We still keep the free-analysis metadata row described above. Abuse-prevention counters store a hash of your IP for about 24 hours and do not keep the raw address on that path. The raw IP is stored only if you later request a score email.
Patent PreCheck is a web service that helps software developers assess patentability and prepare filing-ready materials. Our companion Chrome extension journals AI-assisted invention sessions locally and guides copyright and provisional patent filing prep. Patent PreCheck is not a law firm and does not provide legal advice.

The Patent PreCheck Chrome extension processes the following data in your browser and stores it using Chrome’s local storage API on your device unless you separately choose to submit content on patentprecheck.com:
By default this data stays on your device and is not transmitted to Patent PreCheck servers. If you run a free or paid analysis on patentprecheck.com, import a report, or use assisted filing features you initiate from the extension dashboard, the data you submit there is handled under the website sections of this policy.
If you create an account or subscribe to a paid plan, we collect:
On our public marketing pages (for example, the homepage, pricing, and blog), we use Google Analytics 4 to understand aggregate traffic — page views, referrers, and general device/browser categories. Google may set cookies or use similar technologies; see Google’s Privacy Policy and Google Analytics opt-out. We do not send your pasted invention code, coach answers, or paid-session content to Google Analytics.
If we run paid advertising, we may also use Google Ads conversion tags and the Meta (Facebook) Pixel on marketing and checkout-confirmation pages to measure sign-ups and purchases. Those tools may set cookies or use similar technologies when enabled. We pass only campaign attribution (for example, which ad you clicked) — not your invention source code — to our own signup and lead-capture systems. You can limit ad tracking through your browser settings, Meta ad preferences, or Google ad settings.
We use this data only to improve the product (for example, which pages help people start a free score). It is not sold and is not used for advertising retargeting.
We do not sell your data. We do not use your conversation content for advertising. We do not train AI models on your data.
This section applies specifically to the paid Interactive Code Review service. It is separate from the free Patent PreCheck Score, where your uploaded code is analyzed and immediately discarded without ever being stored on our servers.
When you purchase and use an Interactive Code Review, we store the following on our servers:
paste_input) — including text fetched from GitHub paths you selectNote: Drawing uploads you add during a session are stored as part of your filing package deliverables and retained under the same Session Window and deletion policy as your other paid-session data (below).
Paid session content is stored encrypted at rest in our Neon Postgres database. All data is transmitted between your browser and our servers over HTTPS.
If you ask us to email your free Patent PreCheck score, we store: the email address you provide; the score metadata generated by our engine (patentability score, filing readiness score, five USPTO requirement scores (§101–§112), top recommendations, narrative summary, technical domain hint, and report identifiers); the timestamp of your check; whether you opted in to legal-change alerts; a record of any unsubscribe request; the IP address we saw when you requested the email (used for abuse throttling); and campaign attribution when the browser sends it (UTM parameters, click IDs such as gclid / fbclid / msclkid, landing path, and referring URL).
We do not store the code, document, or content you submitted for the free analysis. That input is processed on our servers for scoring and discarded once your score is generated. If you used GitHub import, we may retain repo/ref/path metadata (not file contents) with your report so you can re-import at signup.
We use this information to (a) deliver the score email you requested, (b) send legal-change alerts if you opted in, (c) stop further email when you unsubscribe, and (d) process self-serve and emailed deletion requests. Unsubscribe suppresses contact and retains the record. We do not sell, rent, or share this information with third parties except as described under Data sharing.
When we email your score, we include a “View online” link of the form https://patentprecheck.com/r/{token}. The token is a cryptographically random 32-character identifier that cannot reasonably be guessed. Anyone with the link can view the report; treat the link as sensitive. You can revoke an individual link from the report page at any time. Unsubscribing stops further email to that address for that report; it does not delete the address, IP, attribution, or the joined report.
The unsubscribe link in any email stops further score and alert email for that report. It does not delete your address, IP, attribution, or joined reports.
Every email we send also carries a “Delete my data” link. It opens your account area at /projects. A signed link (valid 24 hours) or a fresh magic-link email authenticates you; there is no password login. You then choose what to delete: all of it, or individual items (for example three of ten Interactive Code Reviews). Before anything is removed we show a confirmation listing exactly what each selection includes. The confirmation button reads YES, delete these items, with This cannot be reversed beneath it. Prefetching the emailed link does not delete anything.
You can also email info@patentprecheck.com from the address you want removed. We process those requests within 30 days.
Two things survive a deletion, deliberately. We keep a one-way cryptographic hash of your email address so we can honour a do-not-contact request without holding the address itself, and we may retain payment records our accounting obligations require. Deleting a record does not cancel or refund a Stripe subscription or purchase. Cancel any active subscription first, and contact us about billing. A later submission of the same address with consent starts a new record.
We do not sell or share your personal data with third parties, except:
We do not share your conversation content, journal entries, or filing data with any third party under any circumstances.
When the extension is available, conversation content and journal entries will be stored in Chrome's local storage on your device — not transmitted to our servers. Account data (name, email, billing) for the web service is stored on secure servers with industry-standard encryption. We use HTTPS for all data transmission.
Patent PreCheck is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us.
We may update this Privacy Policy from time to time. We will notify you of material changes by updating the date at the top of this page and, for significant changes, by email if you have an account with us.
